工业吊扇的散热结构Heat dissipation structure of industrial ceiling fan

技术领域technical field

本发明关于一种散热结构，尤指一种能够将灯具与吊扇马达整合并构，同步进行废热传导与排除的工业吊扇的散热结构。The present invention relates to a heat dissipation structure, in particular to a heat dissipation structure for an industrial ceiling fan that can integrate a lamp and a ceiling fan motor to conduct waste heat conduction and removal synchronously.

背景技术Background technique

现今大型工业吊扇的应用领域，除了宽广的室内公共空间、礼堂、购物中心之外，还会应用在工厂的大型厂房、仓储厂房等处，借此改善宽广大空间中如何快速空调均温及散热问题，使身处此空间的人们可以有效地获得舒适度极佳的大面积吹拂风场，令体感温度可控制降低。然而，大型工业吊扇因吊扇叶片的直径占幅有3米至8米大小，所以在吊扇上方的空间照明就会受到阻碍，灯具无法装设在吊扇上方，这样会使得扇叶旋转的影子投落在吊扇下方，造成一明一暗的间隔挥影，对视觉感受不佳，所以灯具必须装设在吊扇下方，这样才能避免吊扇扇叶转动时的影子投射。而大型工业吊扇所使用的PMSM马达，其内部的转子是采用强力永久磁铁(例如铷铁硼磁铁)来与定子产生磁场作用，但是过高的温度是永久磁铁的致命伤，会造成其磁性减弱，使吊扇的功率下降。因此，要如何兼顾灯具散热与吊扇的马达散热，即为本发明所要积极克服的课题。Nowadays, the application field of large industrial ceiling fans, in addition to wide indoor public spaces, auditoriums, shopping centers, will also be used in large factories, warehouses, etc. Therefore, people in this space can effectively obtain a large-area blowing wind field with excellent comfort, so that the body temperature can be controlled to reduce. However, for large industrial ceiling fans, the diameter of the ceiling fan blades is 3 meters to 8 meters, so the lighting in the space above the ceiling fans will be hindered, and the lamps cannot be installed above the ceiling fans, which will cause the shadow of the fan blades to fall. Under the ceiling fan, the shadows are separated by light and dark, which is not good for the visual experience. Therefore, the lamps must be installed under the ceiling fan, so as to avoid the shadow projection when the fan blades of the ceiling fan rotate. In the PMSM motor used in large industrial ceiling fans, the rotor inside uses strong permanent magnets (such as rubidium iron boron magnets) to generate a magnetic field with the stator. However, excessive temperature is a fatal injury to the permanent magnets, which will cause its magnetism to weaken. , which reduces the power of the ceiling fan. Therefore, how to take into account the heat dissipation of the lamps and the motor of the ceiling fan is a problem to be actively overcome by the present invention.
